Edible oil and edible oil refining machines are divided into batch type, semi-continuous type and full continuous type.
The function of the edible oil refining machine is to remove harmful impurities from the crude oil, to ensure that the color, transparency, taste, stability, fatty acid composition and nutritional components of the edible oil meet certain quality standards, which is essential in the edible oil production line of.
Crude oil → degumming → deacidification → decolorization → filtration → deodorization → filtration → fractionation/winterization/dewaxing (optional) → refined oil
Alkali refining pot in edible oil refining machines: remove impurities such as phospholipids and free fatty acids. Alkali refining pot, also called refining pot, is used for hydration degumming, neutralization and deacidification of oil. Alkali pan degumming firstly preheats the oil to 60-70°C, adds concentrated phosphoric acid of 0.05%-0.2% of the oil mass, mixes fully in the mixer, and stays in the temporary storage tank for a while, then adds 1%-5 % water for hydration, and then centrifuged, the oil is dehydrated and then decolorized with activated clay. Alkali deacidification is to add caustic soda to the alkali kettle to neutralize the free fatty acid to produce soap, and then separate the soap from the oil.
Decolorization pan in edible oil refining machine: removes pigment. The decolorizing pot first needs to add a decolorizing agent accounting for 1-3% of the oil weight (mainly clay), for physical adsorption, and then filter equipment to separate the oil from the decolorizing agent, so as to achieve the purpose of decolorizing.
Deodorization pot in edible oil refining machine: to remove the peculiar smell in the oil. Under a high temperature of 220-260°C and a certain vacuum condition, a certain amount of superheated steam needs to be introduced into the deodorization pot to strip the oil, and the purpose of deodorization is achieved according to the difference in the volatilization point of the oil and volatile small molecular substances. Because the temperature during deodorization will reach about 260 degrees, the carbon steel material of the deodorization pot may produce harmful substances at high temperature, so the deodorization pot of Dayang Company is made of stainless steel to ensure the quality of the refined oil.
Filters in edible oil refining machines: remove impurities and decolorizing agents from oils and fats.
Vacuum pump: create a negative pressure vacuum environment for the decolorization pot and deodorization pot.
Heat conduction oil furnace: provide heat source
In order to meet the needs of customers with different processing volumes, Dayang Company can provide you with 1-20 tons/day intermittent edible oil refining machines, 10-50 tons/day semi-continuous edible oil semi-continuous refining machines and 50 tons/day There are three types of continuous edible oil refining machines. Of course, these three types of edible oil refining equipment have their own advantages, and you can choose one according to your specific needs.
Intermittent edible oil refining machine: simple and flexible operation, low investment, suitable for frequent replacement of various oils, suitable for manufacturers with small processing volume.
Semi-continuous edible oil refining machine: The degumming and decolorization section is intermittent production, or decolorization can be continuous. The deacidification and deodorization section adopts deodorization tower process for continuous production, which can realize continuous refining, high efficiency, energy saving, economy, and high additional output value. .
Fully continuous edible oil refining machine: It can realize continuous and uninterrupted production in all sections, with low production consumption, low oil loss, and more stable refined oil quality. For the deacidification and deodorization section of continuous refining, choose a single tower, or choose a double tower coupled production process
According to the type of crude oil and the size of the processing volume, the engineers of Ocean Oil can customize a set of edible oil refining machine for you. For more than ten years, Dayang Oils has been adhering to the business philosophy of "quality first, integrity first". The edible oil equipment has reliable quality and has been exported to more than 90 countries and regions abroad. It is committed to redefining "intelligent manufacturing in China" with first-class technical products Connotation.
